This is thoroughly good news but of course it’s the combination of performance allied to the colossal 2TB capacity that catches the eye. That said, the formatted capacity is a ‘mere’ 1863GB.

The problem, however, is that you’re paying a whopping great premium of £50 for the Black drive compared to the 2TB Green. Alternatively, you can buy the 1.5TB Green for £87 which sounds like something of a bargain compared to the £150 2TB version, let alone the £204 Black.

The other problem for WD is that Seagate has just announced its new 2TB Barracuda XT with 6Gb/s Sata interface. This is very tempting if you’re building your PC around a new Intel P55 motherboard as it has a 6Gb/s Sata controller. The Barracuda XT is priced at the same level as the Caviar Black so WD's 3Gb/s Sata drive might be seen as the end of an era.
